The reduction is not as straightforward as applying a percentage reduction back from age 65. In order to work it out, a number of general assumptions have to be made, including:
- whether or not the member is likely to be married when they die
- how long the member (and any spouse) would be expected to live
- what the average rate of inflation might be throughout the member’s (and any spouse’s) future lifetime, both before and after retirement (this determines the rate of pension increases in the future)
- the average rate of investment returns that any cash sum invested in the Scheme at the date of retirement would be expected to earn over the member’s (and any spouse’s) future lifetime.
The reduction is calculated by the Scheme actuary on a ‘cost neutral’ basis. This means that, taking all members in total, the Scheme should make neither a gain nor a loss as a result of members retiring early.
